thought I'd repost a pic of a couple of ideas to solar heat water... in 2004 I was without power for about 6 1/2 days, and hot water heater cooled at about day 2...city water was not interrupted simply run it through your garden hose but limit the flow rate with a nozzle...125' of 7/8" hose holds about 2 1/2 gal, and can get to 135F in about an hour in Florida summer...be careful black painted garden sprayer for shower water pressure 3mil 33gal trash can liner, laid open end over a 2x4 will hold 5 gal of water and reach 125F+ in 1 hr... you must dip the hot water out of the bag as it has a serious scald potential  if you are new to hurricane land, have lots of tips

Regarding improvised solar heated showers, as noted above the water can easily become too hot.
Might it be worth the use of a thermostatic mixing valve ? These are widely available from plumbing supply houses.
They only work if you have a supply of hot and cold water, both under pressure.
But in the example given of a length of black hose in the sun, and fed from a pressurised supply, a second cold supply and a thermostatic valve should give good results.
Another option is a 12 volt submersible pump and a drum of warm water. This has the merit that the temperature of the water in the drum wont change significantly during the shower, and can of course be adjusted before hand.

Or just empty the hose into a bucket and add cold water until you reach a nice temp.

Why improvise a solar heated shower? Nice units are readily available. My experience is that they work very well. We did a field project in which we filled our showers as we left camp for work in the morning, returning to pleasantly warm bags in the late afternoon (summer and fall conditions). This procedure worked well for four of us, eight days consecutively for about three months. I got to the point where 2 1/2 gallons per shower was more than enough. I have also used the showers by heating water on a stove and mixing to the correct temperature. They are great items that are compact, workable, and fine morale boosters.

MDinana...that's what I do with the garden sprayer...
hikermor... I don't have room to hang the gravity bags in my shower...actually I have room, but I place a 33gal plastic trash can in the shower to hold non potable water, and my room is limited... the sprayer is convenient to mix, transport, and provide water pressure
after the long power outage in 2004, I did an after action debrief with my kids.... the lack of hot shower and batteries for their entertainment gizmos was the most common complaints... the trash bag was investigated for use by those in condo/apartments without access to garden hose...

i'm fascinated by this new shopping concept of "back to school and hurricane supplies". I'm shocked that Walmart doesn't offer a special like this :-)

most years the state of Florida offers tax free days for both school and hurricane supplies...

a thread on another forum got me thinking about a 12v battery power station... I don't really need a 120V inverter, as I've pretty much converted to 12Vdc... so I just got home with a deep cycle trolling motor battery to work with my fans, mini TV, and Eneloop recharger....also picked up another 12Vdc power tap... last week ordered some of the AA to D adapters, ones that take 2 of the AAs... to see if I can get 6 hours on my ceiling fan running off AAs
under Electronics for DUMMIES... if you try to hook up your digital portable to your cable, make sure it attaches to the cable source and not out of the DVR box... dumb.. dumb...dumb....
